Hi @fzhan51​ , When you say 1x40G, it is only 1 port at 40G, right?

Or, Do you mean 4x10G instead? Because the the card can only support 10G per port.

1 port at 40G --> it makes sense it will FAIL because the card supports 10G per port

4 port at 10G each --> it makes sense it will PASS because the card supports 10G per port

 

Im not sure there is such cable as 1 port at 10G --> then this will further confirm my explanation.

 

Btw, 1x40G is NOT EQUAL to 4x10G !!
